ABSTRACT
Objective: To investigate the assessment of patients with functional ankle instability prior to and post of regular rehabilitation therapies. Methods: One hundred and twenty-four patients with unilateral chronic ankle instability (51 females and 73 males, age 34-56) were received conventional rehabilitation for two month, including muscle strength, range of joint motion, balance, proprioception, etc. The visual analogue scale (V AS) scores (instant pain and pain after 500-meter walk) were recorded. Standing time of affected limb, the star excursion balance test, static and dynamic plantar pressure were performed. Results: There were significant differences in VAS pain score of instant pain (5. 32 ±0.27 vs 1. 07 ± 0. 08) and after 500 meter walk (8. 79 ± 1. 78 vs 4. 51 ± 1. 78) (P 0. 05). Conclusion: Rehabilitation therapy can significantly improve the pain-release, the balance, etc. However, the effect on the dynamic response is not accurate. Thus, the abnormal of walking posture, the biomechanics of the foot and ankle, and biomechanics of functional ankle instability should be considered during the rehabilitation treatment.
